Supporting that system is problematic for us, since we don't have 10.5 systems available for dev/test. Currently, the build/test farm is OS X 10.7. I don't think this is like the Windows issue. Upgrading Windows is (for me, anyway) a full day job. Upgrading OS X is inexpensive and relatively painless, the least painless of any system newer than DOS that I've experienced. Hence, is it worthwhile to continue support for 10.5? Can we officially say that only 10.6+ is supported? Is there a significant 10.5 community that eschews OS upgrades but still expects new apps? There appears to be fewer 10.5 users than 10.4, oddly: http://update.omnigroup.com/
Note that 10.5 and 10.4 support PowerPC as well as x86. They have 4% PowerPC, down from about 7% at the start of 2011. That accounts for about 25% of the combined decline of 10.4 and 10.5, and it's clearly caused by old machines being replaced. They must date from 2006 or earlier. Surely a large fraction of the remaining 10.4 & 10.5 systems are likewise near end of life.
So it looks like: 48% 10.7 34% 10.6 15% 10.5 + 10.4 4% PowerPC, never supported by DMD.
